Box-Death Hollow Wilderness and Phipps-Death Hollow ISA Trails Professional Review and Guide
"Death Hollow is in the high country where the Escalante River has its headwaters. The Escalante and all its tributary streams feed the Colorado River in Glen Canyon National Recreation Area. More than 6,000 feet in elevation change from the Aquarius Plateau to the Colorado River makes for some deeply incised canyons. “The Box” of Box–Death Hollow Wilderness is a narrow canyon holding Pine Creek in its tight confines. In places the walls of The Box are 1,500 feet high. At its upper elevations, Douglas fir and ponderosa pine forests provide an almost impenetrable shade. Douglas firs give way to scattered ponderosas, aspens, wild roses, and finally sagebrush and cottonwoods as hikers descend along the creek. Hiking The Box requires multiple creek crossings.
In the spring, snowmelt swells the creek and boulder-hopping is much more difficult. The ability to walk narrow and shaky logs is helpful. Later in the season, when high water abates, the hike is easier and temperatures are still tolerable, especially in the shaded upper portion. This 8-mile day hike is the only official trail in Box–Death Hollow Wilderness. This trail guide includes descriptions of Upper Calf Creek Falls, Lower Calf Creek Falls, and Boulder Mail Trail."
